      If your version of Norton AntiVirus 3.0 for Windows and DOS is dated
      before June 9, 1995, you will need to update it using the NAV July 1995
      Update in order to use these virus definitions. If you have not
      updated your version, download the NAV July 1995 Update from the
      Symantec BBS, CompuServe, or America Online. The file is called
      UPDATEME.EXE and is located where the monthly update files are
      normally found. Alternately, you may call Customer Service at (800)
      441-7234 to obtain the NAV July 1995 Update disk.

                          Loading New Definitions

NOTE:  The new definition files contained in this .ZIP file replace the
       corresponding Norton AntiVirus 3.0 files. Only the most recent virus
       definitions are required to fully update your copy of Norton
       AntiVirus 3.0.

============================================================================

To update Norton AntiVirus for Windows 95 virus definitions:

1)  Double-click the "My Computer" icon on the desktop.
    The My Computer window opens displaying your available drives.

2)  Double-click the drive or director that contains the Norton AntiVirus 
    Definitions Update.

3)  Double-click the Nav30 folder.
    The list of definition update files is displayed.

4)  Copy the following files to your Norton AntiVirus for Windows 95
    folder. By default, this is the C:\Program Files\Norton AntiVirus
    folder:

         VIRSCAN.DAT
         VIRSCAN.INF
         VIRSPWD.DAT

    For instructions on how to install the definition files from the DOS
    prompt, see the additional update instructions below.

5)  Launch Norton AntiVirus, then scan your drives.

    Each update contains detection for newly discovered viruses.
    Performing a virus scan will also force Norton AntiVirus to recognize
    that a new VIRSCAN.DAT file is in place.

6)  Restart your computer so that the Automatic Protection TSR uses the
    newest virus definitions.

==========================================================================

To update Norton AntiVirus 3.0 virus definitions:

     1.  Copy VIRSCAN.DAT, VIRSCAN.INF, VIRSPWD.DAT and VIRSPEC.TXT into 
         the Norton AntiVirus 3.0 directory.

     2.  Scan a drive, directory, or file with Norton AntiVirus 3.0, in
         either DOS or Windows.

         This will generate new interim files and update the automatic
         protection TSR.

     3.  Reboot your computer to load the updated automatic protection
         TSR.

TIP:  If you unzipped this file inside your \NAV directory, (\NDW for
      users of Norton Desktop for Windows), then step 1 is already
      completed. If you unzipped this file in a different directory, copy
      the extracted files to your \NAV directory. If prompted to overwrite
      existing files, select Yes.
